This study has been conducted to design and implement smart phone-based application which can keep records effectively to improve athletes' ability. To boost their performance, they need to receive training as realistic as possible. As a way to do that, training should be performed with some fitness equipments, sporting apparatus, facilities, and conditions. However, it is also possible to improve their ability by motivating athletes with checking and recording their performance. This study ascertains that using scoring records actually motivates athletes when comparing the result of youth basketball team using the records keeping system with that of not using it. Accordingly, smart phone-based records keeping application has been designed and developed. Also, through a survey targeting athletic coaches who have used the system, training efficiency has been measured and it turns out that it actually motivates athletes to improve their abilities.

2013년도에 자전거 판매량이 100 만대를 돌파하면서 자전거 운동에 대한 사람들의 관심이 증가하고 있다. 뿐만 아니라, 서울시 등 각 지방 자치에서 자전거 도로를 설치하고 자전거 코스를 제공하는 등 국민의 건강관리에 힘쓰고 있다. 자전거를 통한 건강관리에 대한 관심이 증대되면서 스마트 디바이스를 활용한 운동 관련 어플리케이션도 역시 증가하고 있다. 본인의 기록을 측정하기 어렵고 별도의 장비가 필요하던 과거와 달리 이제는 누구나 가지고 있는 스마트폰만으로도 자신의 운동을 효율적으로 자신의 운동을 관리할 수 있도록 하는 어플리케이션이 인기를 끌고 있다. 이러한 수요에 맞추어 스마트 상의 GPS 센서를 이용한 자전거 가이드 시스템 '자전거로 달려볼까'는 별도의 센서를 부착할 필요 없이 스마트폰에 기본적으로 포함되어 있는 GPS 센서를 이용하여 사용자에게 운동 기록 측정, 기록 보기, 코스 및 날씨정보를 제공한다.

The purpose of this study is to promote future research and practical application in the field of records systems by informing the revision of the ISO 16175 standard set and analyzing its main contents, which was widely used as a record management functional requirements. Based on the experience of participating in the developing process of this International Standard since 2015, this study analyzed the context and process of revision, and the main contents of the standard, and sought to draw limited implications and proposed follow-up researches connected to the practice of the Korean records systems. The previous ISO 16175 sets had been produced as ISO 16175-1, 2, 3 in 2010-2011, and which were restructured and revised into new ISO 16175-1, 2 in 2020 in line with the revision of ISO 15489 and changes in the digital environment. Main title of the International Standard is processes and functional requirements for software for managing records, and Part I provides high-level functional requirements and associated guidance for applications that manage digital records, Part II provides guidance for selecting, designing, implementing and maintaining software for managing records. This standard assumes that the records system does not necessarily have to be a single system or software solely for records management and that it should be able to perform record management function in any forms.

Plumbing of the plant project is an important discipline. Now workers on the construction site, carry hundreds of piping spool drawings and documents, record the Spool Stage data. Then, The data is input into the system or has been documented in the field office. Because of the work-flow, duplication work occurs. As a result, it is reducing the effectiveness of the Plumbing and causes schedule delays. Also, To manage the integration process, there is a problem, it takes a lot of time. Therefore, The study is conducted to design and implementation of piping spool management Android Application using QR Code. The Application will contribute to the management to the integration of piping work process.

The present study aimed at investigating the strengths and weaknesses of a mobile personal health record (PHR) application and identifying its impacts on consumer health information behavior. For the study, twenty-seven college students used a PHR application for three months, based on which the study conducted paper-based interviews with them. The results of content analysis highlighted the benefits of the PHR such as supporting preventive healthcare and motivating and providing specific guidelines for healthy lifestyles by utilizing visual interface design, sharing the data with family and assisting caregivers to manage patients' healthcare, and above all enhancing the interaction between patients and healthcare professionals. However, the study found the drawbacks of the PHR such as a lack of data entry for strength training and the incompatibility with other healthcare applications. The participants were motivated to change their health behaviors in ways such as getting rid of sleep disorders, avoiding alcohol and smoking tobacco, and losing weight, and changing eating habits. Some consumers improved self-efficacy by changing their health behaviors, while the PHR provided emotional supports to the consumers who wanted to improve their health. The present study has an academic significance because the study of PHR is a burgeoning area in Korea. The study provides insights for promoting health and medical information services to cope with the paradigm shift of healthcare fields.

Recently, there are several attempts to save temporal, spatial and paper resources through mobile teleconference. However, present application-based mobile solutions have limited access, and are occasionally not working because of its operating system dependency. In recent times, several researchers attempt to develop mobile teleconference systems that can operate in all operating systems. It is still required to install proprietary applications to sync screens in user device. In this paper, we propose a full duplex and real-time data mirroring technology based on hybrid web that allows syncing screens without application installation, and operates in all mobile devices.
